The specific embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

Carton device for folding of the present utility model please refer to Fig. 3 to shown in Figure 5, in order to amount to moulding one carton cardboard 9, it comprises that a conveying device 1, a bending device 2 and are arranged at the impression shaped device 3 in the bending device 2, mainly respectively form an impression 92 in cardboard 9 broken lines 91 both sides to destroy the paperboard structure and the intensity thereof of broken line 91 both sides by this impression shaped device 3, make the cardboard box structure that utilizes this carton device for folding moulding in the process of cardboard 9 bendings, allow broken line 91 keep its both allocation, be unlikely to skew and influence whole carton finished size and outward appearance.

Wherein, this conveying device 1 comprises on one the paper folding wing 11 and the paper folding wing 12 once, in the utilization paper folding wing 11 and down the paper folding wing 12 with the cardboard clipping and stablely carry towards bending device 2 directions.

This bending device 2 is arranged at a side of the upper and lower paper folding

wing

11,12, comprise a guide rod 21, when cardboard 9 contacts with guide rod 21, guide rod 21 can form cardboard 9 bending of certain angle, and moulding one

broken line

91, and 21 one-tenth irregular bendings of this guide rod can slowly be amounted to into cardboard 9 plane.

This impression shaped device 3, be arranged in the bending device 2, and be positioned at when guide rod 21 with cardboard 9 be bent to angle less than 90 the degree parts, it comprises that compacting wheel 31 and one external pressure ratch 32 also is fixedly arranged on respectively in one, the following paper folding wing 11, on the 12 set connecting plates 111 and connecting rod 121, and this external pressure ratch 32 is more driven by a drive unit 33 and a belt group 34, wherein, the wheel face external form cross section of interior compacting wheel 31 has two right angles, the wheel face of external pressure ratch 32 is concaved with a tool two

lopsided grooves

321, and 31 on external pressure ratch 32 and interior compacting wheel and form the gap of a feedboard 9 walkings, in present embodiment, drive the impression shaped device in addition, also can not need drive unit to drive equally certainly and can reach identical purpose with drive unit.

During actual enforcement, main utilize go up the paper folding wing 11 and down the paper folding wing 12 be delivered to the processing of bending device 2 places with cardboard 9 is stable, when contacting with guide rod 21, cardboard 9 cardboard 9 can be formed the bending of certain angle, with moulding one broken line 91, cardboard 9 continues to carry toward impression shaped device 3 directions afterwards, driving external pressure ratch 32 by drive unit 33 rotates, cardboard 9 continuation this moment are carried and are taken turns 31 through external pressure ratch 32 and interior compacting, the right angle of compacting wheel 31 wheel faces is resisted against cardboard 9 broken lines 91 both sides respectively in making, make each roll extrusion of 91 both sides of cardboard 9 broken lines form an impression 92 (as shown in Figure 5) to destroy the paperboard structure and the intensity thereof of broken line 91 both sides, moreover, cardboard 9 will continue via carrying guide rod 21 and its cardboard 9 slowly being amounted to into plane carton (as shown in Figure 6), and the cardboard box structure that utilizes this carton device for folding moulding is in the process of cardboard 9 bendings, can allow broken line 91 keep its both allocation, be unlikely to skew and influence whole carton finished size and outward appearance (as shown in Figure 7).

In addition, please refer to shown in Figure 8, in this bending device 2, can further be provided with a shaping guide wheel device 4, this shaping guide wheel device 4 is arranged at impression shaped device 3 the same sides (impression shaped device 3 and shaping guide wheel device 4 are side by side) and is positioned at when guide rod 21 is bent to angle with cardboard 9 spends parts less than 90, it is made up of inner guide pulley group 41 and outer guide wheel group 42 that axis direction is parallel to each other, and be fixedly arranged on respectively, the following paper folding wing 11, on the 12 set connecting plates 111 and connecting rod 121, and in, outer

guide wheel group

41,42 respectively by in more than one, outer guide wheel 411,421 form, and each outer guide wheel 421 of this outer guide wheel group 42 and external pressure ratch 32 are by same drive unit 33 (can be motor), an one belt group 34 and an idle pulley group 35 drive, as shown in Figure 9.

As shown in figure 10, wherein, the wheel face external form cross section of each inner guide pulley 411 is diamondwise slightly, and the minor axis place of rhombus is the axle center 412 of inner guide pulley, the major axis place of its rhombus then is a cam surface 413, and the profile of each outer guide wheel 421 of outer guide wheel group 42 cooperates the wheel face external form of inner guide pulley 411, be concaved with the groove 422 of a tool two inclined sides 423 in the wheel face of outer guide wheel 421, make 422 of cam surface 413 and grooves form the bending gap B of a feedboard 9 walkings, cam surface 413 and groove 422 be resisted against respectively cardboard 9 in, the outside, and by its formed angle with cardboard 9 bending typing.

Moreover, the minor axis place of inner guide pulley 411 is in regular turn gradually little, make inner guide pulley 411 more and more flat, extremely shown in Figure 12 as Figure 10, and outer guide wheel 421 also changes with the wheel face of inner guide pulley 411, make the angle of 423 of two inclined sides of groove 422 gradually little, and then make the bending angle of this bending gap B gradually little, and then make cardboard 9 bendings gradually in plane, utilize guide rod 21 to amount to into cardboard 9 plane at last again, as shown in Figure 6, so shaping guide wheel device 40 can reach cardboard 9 effect of shaping and typing in the process of amounting to, and make the bending place of cardboard 9 unlikely crooked.
